Abstract
An endovascular system for arresting a patient's heart and maintaining the patient on cardiopulmonary bypass. A venous cannula, venting catheter and an aortic occlusion device are all coupled together so that the blood drawn into each of these catheters may be fed to a pump. A manifold has valves which control flows through the venous cannula, venting catheter and aortic occlusion device. A blood storage element is also provided so that the amount of blood in the perfusion circuit may be varied if necessary. The blood storage element is preferably positioned in parallel with the pump so that the pump may be used to add and remove blood to and from the blood storage element.
